This assumes the construction of these 50-100 year buildings were evenly distributed over a given time. If 90% of a towns or cities 100 year infrastructure if built in a decade, then it'll just lead to a lot of replacements starting in about 90 years, not continuous small replacements.

- seoaeu 4y agoMore likely once the 90 years expires the area discovers that it is not actually capable of doing the replacements required. Of course, pretty much only suburban areas have infrastructure/buildings built over that short an interval. Constructing 90% of a major city’s high rises in a decade would be a construction boom unlike anything the western world has seen in a lifetime.

Lifespan of a building isn't some kind of magical threshold thing where it is perfect for 100 years and then must be replaced in year 101. A noticeable share of those buildings built for 50 years will need to be replaced around years 25-30. Almost all of those buildings will need work before 20 years is up. Some of them will outlast their design life by a large factor. Not to mention that not every builder is selecting the same construction techniques and design life.
